An article published in the journal “Icarus” reports a study on the frozen crust on the surface of Enceladus, the moon of Saturn which has an ocean of liquid water under its crust. A team of researchers analyzed data collected by the Cassini space probe’s Visible and Infrared Mapping Spectrometer (VIMS) instrument to obtain the most detailed infrared map of Enceladus’s surface. The map shows a clear correlation between reflected infrared emissions and geological activity, and in some areas, the surface ice turns out to be recent.
